SEWAGE PURIFIER.

Application filed. October 9, 1919. Serial No. 329,559.

To all whom it 'nmy con/Jami:

Be it known that I, JOHN P. BALL, a citizen of United States, residing in the ci y of Chicago, in the county of (look, in the State of Illinois, United States of Amer-- ica, have invented. a certain new and use ful Improvement in Sewage Purifiers, of which the following is a specification.

This invention relates to a device for separating, purifying, classifying, treating or collecting sewage by utilizing a fluid cur rent and aims to provide certain improve ments therein.

My invention provides improvements pccially applicable to devices of this general character and in its preferred form it utilizes a sludge collecting chamber, an initial agitator and aerating means comprising a blower supplying air to the sludge to be treated, a discharge opening in conjunction with a collector consisting of a plurality of superimposed annular conical receiving chambers, a reverse return passage for each receiving chamber, and a final air discharge column, all of which will be herein more fully set forth. I

Figure 1 is a vertical cross-sectional view of the preferred form of my invention.

Figure 2 is a to plan view of the pre ferred form of my lnvention, portion of the top or covering means being brokenaway so as to show the internal mechanism.

Referring to the drawings, A indicates a sludge collecting chamber, an intake pipe B supplying the sludge to be treated, the chamber being in turn provided with a revolvably mounted agitator C, and also provided with a fan or blower D, the agitator and fan being intended to produce by combined action a fluid current of aerated sludge. E represents'thepowerimparting mechanism whereby the air forcing means and agitating means may be'operated. F is an annular discharge passage conical or of nozzle form through which the current passes. G is a collecting member consisting ofv a plurality of conical: shaped receiving chambers, each chamber having a suitable exposed surface so as to receive and collectthe suspended matter from the sludge laden fluid current. H isthe final exhaust passage outlet whereby the noxious gases generated may be liberated and discharged into the atmosphere at an elevated plane preferably above the house top.

Referring to Figure 1, I will now describe in detail the preferred. form of my invention. The sludge chamber A has a cylindrical body a?, a closed flat bottom 7) and a flat annular open top 05; The body, top and bottom are bolted or riveted together to form a receiving chamber for the liquid sludge. The supply pipe B is pret erably an iron pipe entering the chamber through an opening in the casing at f. This intake pipe is provided with a check valve g at the point of contact. Where the intake pipe enters the casing is a sealed joint so as to form an air tight connecting joint. The driving mechanism E shown consists of a driving shaft it carrying fast and. loose pulleys and geared to the driven parts by'bevel gears. This shaft is mounted in hearings in the frame 7', which frame is shown as crossing the machine and supported on'the concrete base at each side thereof, and the entire mechanical operatingdevice'as shown is suspended from the frame, which has one face coinciding with the diametric parting of the body. The agitator C is preferably a plurality of cir cular plates m mounted and keyed to the shaft Z. The fan shaped blower D is also mounted and keyed to the shaft Z? The blower and the agitator revolve with the shaft Z bymeans of the geared wheels at a. The collecting chamher G is a casing constructed preferably of sheet metal, rivetedso as to make air tight joints. It has a cylindrical body p with a flat top and bottom a and 2"respe-'rtively. The sides of the chamber are pro the collecting chambers and forms a free passage thereto.

It is constructed preferably of sheet metal riveted so as to form a cylindrical or conical body. The 'three chambers may be bolted together by iron rods so as to form one continuous casing.

The collector is preferably astationary member. It comprises a plurality of 'concentric conical. cups, eachv cup being separated by a series of baffles. each bafliebeing molded so as to form'a symmetrical mesh of the whole. The concentric cups are lettered :0 and therespective battles are lettered 00'. The bafi'le members m are also somewhat in the nature of cones with the apexes thereof preferably secured to a single rodor member m which is removably secured and depends from the top member 9" of the collecting chamber G. lVith this construc tion, it is evident that when the top or the chamber is removed, all. oi the battle mem bers likewise will be withdrawn tromtheir telescopic relation with the cup members, thus permitting access to the bai'iles and the cup members for cleaning and repair. The cups and battles in place form the reverse and return passagesfiy.

The surface of the cups and battles is covered with a suitable material to collect the atoms from the sludge laden fiuidcurrent. In the preferred form of my invention a fibrous material such as cheese cloth is used as a covering on the said cups and battles.

The battle conical shaped. cups are prefer ably constructed of fibrous material suitable to collect the suspended matter in the fluid current.

. The final exhaust chamber H is constructed preferably of sheet metal and in the form of a cylindrical stack, the top or outlet being preferably located at an elevated plane and the stack forms a continuous chamber fronr the'aerating chamber to the outlet. In this exhaust chamber a damper is constructed by the disk I which regulates the exhaust current.

At a point of connection between the exhaust chamber and the aerating chamber a conicalshaped screen y of wire mesh is constructed so as to intercept any remaining atoms passing through the collector.

By shutting off the supply of sewage and by continuing the blower, the collected sludge may be air dried in the receiving cups.

It will be understood that the invention is not limited to-the particular details of construction, arrangement and combination setforth, as it can be employed in whole or in part according to any modifications.

It will be understood that by closing the valve the flow of sludge into the basin A is shut off. The fan D is then set in operation and in time the sludge in the basin A will be dissipated and lodging in the mesh and 1 of the chamber G, will be dried by V a clrcultous current of air from the continu ousrevolutions ofthe fan D. The valve 71:

being then opened the operation is repeated.

What I claim is: I

l. A device for treating sewage, comprismg a' sludge-receiving receptacle, agitating and aerating means mounted in said receptacle, a. collecting chamber arranged in communication \vithsaid receptacle, sai d collecting chamber being formed to provide a circuitous pan for the aerated matter, and a vent leading from said collecting chamber. device for treating sewage, comprismg a phirahty of chambers. means for supplying'liquid sludge to one of said chambers, means for creatlng an air current in said chamber and causing it to pass into a second chamber, means arranged in said second chamber for collecting theaerated liquid passing through the second chamber, means for drying. the collected matter.

4. In a device: for treating sewage, the combination of a receiving chamber for liquid sludge, means for agitating the sludge and creating an air current in said chamber whereby the sludge is aerated,.and means whereby the aerated liquid is made to travel in a circuitous path, said means being arrangd to collect entrained particles. 7

6. A device for treating sewage, comprising a sludge-receiving chamber, a second chamber mounted on the first men'tioned chamber and in communication. therewith, means rotatably mounted inthe first mentioned chamber for agitating the sludge and to induce aeration thereof, the second mentioned chamber being provided with a series of concentricallyarranged conical cups secured to the bottom of saidisecond chamber,

the top of said second mentioned chamber being'provi'ded with a; depending member, a series of concentrically arranged baflie members all secured to said depending members and telescoping with said cup' members whereby the'aera'ted sludge is forced to flow through vertically disposed circuitous path, and means for controlling the aircurrent through said chambers.
